关于空气净化器的论文

专科生毕业设计（论文）I摘要室内空气中的微粒、细菌、病毒和其他有害物质日积月累地损害着人们的身体健康，特别对于那些长期处于室内环境的人。随着生活水平的提高，人们对自己日常生活和工作的室内空气环境质量的要求和期望也在不断提高，室内空气净化技术成为了环境领域的一个新的课题。尤其是在室内空气净化器诞生以后，各种不同类型的空气净化器如雨后春笋般涌现入市场，本论文则是在此背景下研究并设计出一种新型的、利用紫外线杀毒的空气净化器电路控制系统。本论文研究的紫外线空气净化器的控制系统，是基于AVR单片机进行设计、开发与实现的。首先，完成系统功能需求分析，选择合适的ATmegal28单片机，设计出课题研究的空气净化器控制系统的总体结构与工作原理框架；其次，利用TGS800气体传感器与LHi878热释电红外传感器分别检测室内空气质量和移动人体红外信号，并将采集信号输出给单片机端口，单片机根据检测到得各个模块的硬件电路设计，从硬件模块的总体结构出发，分别设计了电源控制、电机控制、紫外灯管控制、液晶显示器控制、红外遥控以及功能按键控制等模块的电路原理与实现，并在此基础上介绍了单片机控制系统的主要功能程序设计，完成了控制系统的试运行与调试。本文研究的这款空气净化器是典型的利用紫外线对空气进行杀菌与消毒的产品，其两个传感器数据采集模块的集成是项目设计的重要创新点之一，他们集成使得本空气净化器具有自动采集与自动调整工作状态的功能，实现了产品的智能化、节能性与环保的特点。该空气净化器电路控制系统的成功研制，必将为室内空气污染控制与空气净化技术作出巨大的贡献。关键词：空气净化器；AVR单片机；控制系统；紫外线；传感器专科生毕业设计（论文）IIAbstractIndoorairparticles,bacteria,virusesandotherharmfulsubstanceshavedamagedtopeople’shealth,especiallyforthosepeopleintheindoorenvironmentinalongtime.Withtheimprovementoflivingstandards,people’sairenvironmentalqualityrequirementsandexpectationsoftheirdailylivesandworkownindoorhavealsoincreasedmisconduct.IndoorairpurificationtechnologyhasbecomeanewfieldofenvironmentalprotectionissuesEspeciallyafterthebirthofindoorair,somanydifferenttypesofairpurifierhavesprungupintothemarke.Inthispaper,anewcircuitsystemofairpurifierwithultravioletdisinfectionhasbeendevelopdinthiscontext.Inthispaper,thecontrolsystemofultravioletair-purifierhasbeendesignedanddevelopedbasedonAVRmicrocontroller.Firstlytherequirementsanalysisofsystemfunctionalhasbeencompleted.ATmegal28microcontrollerhasbeenchoosedtodesigntheairpurifiercontrolsystemstructureandworkingprincipleoftheoverallframeworkofthisresearchproject.Secondly,TGS800gassensorAndLHi878pyroelectricinfraredsensorhavebeenusedtodetectindoorairqualityandmobilityofhumanIRsignal.Hardwarecircuitdesignofeachmoduleofthiscircuitcontrolsystemhasbeendescribedpriorityinthispaper.Theoverallstructureofthehardwaremoduleshasbeendesignedfirstly,andthenthecircuittheoryandimplementationofthemoduleshasbeendesignedfirstly,infraredremotecontrolandfunctionkeyscontrolhavebeendesigned.Onthisbasis,themainfunctionofmicrocomutercontrolsystemprogramminghasbeendiscribed,andthetrialoperationcontrolsystemanddebugginghasbeencompleted.Thistypeair-purifierwhichhasbeenresearchedinthispaper,isatypicalindoorair-purifierfortheuesofultravioletsterilizationanddisinfectionproduct.Thesuccessfuldevelopmentofthisair-purifier’scircuitcontrolsystem,willmakeasignificantcontributionfordoorairpollutioncontrolandairpurificationtechnologyinevitable.Keywords:air-purifier;AVRmicrocontroller;controlsystem;sensor专科生毕业设计（论文）III目录第1章绪论..........................................................................................................11.1课题研究的背景.......................................................................................11.1.1室内空气污染的现状....................................................................11.1.2室内空气净化器的发展现状........................................................11.2研究内容...................................................................................................3第2章空气净化器控制系统的总体设计............................................................52.1AVR单片机简介.......................................................................................52.2ATmega128单片机....................................................................................62.2.1ATmega128的引脚配置.................................................................62.2.2ATmega128主要特性.....................................................................72.3空气净化器控制系统总体设计...............................................................72.3.1空气净化器功能概述....................................................................82.3.2控制系统需求分析........................................................................92.3.3系统总体结构设计......................................................................102.3.4系统工作原理设计......................................................................11第3章传感器数据采集模块设计与实现..........................................................133.1数据采集系统.........................................................................................133.1.1数据采集系统的类型..................................................................133.1.2数据采集系统的结构配置..........................................................133.2气体传感器数据采集模块设计.............................................................143.2.1费加罗TGS气体传感器.............................................................143.2.2TGS800传感器数据采集实现.....................................................163.3红外传感器数据采集模块设计.............................................................213.3.1红外传感器概述..........................................................................213.3.2热释电型红外传感器..................................................................22第4章控制系统的硬件设计与实现..................................................................244.1初控制系统硬件模块总体结构.............................................................244.2选电源控制模块设计.............................................................................254.2.1电源模块结构............................
